Title: Improvements in regulators for electric motors
IPC: H02P7/06
Filed: 1951-10-12
Abstract: 694,077. Automatic speed control systems. DUDENHAUSEN, H. J. Oct. 12, 1951 [Oct. 16, 1950], No. 23819/51. Class 38 (iv). In an automatic regulator of the Tirrill type for controlling the speed of D.C. motors, the electromagnet of the regulator switch is provided with a winding in series with the motor armature in addition to the normal winding connected across the armature. The field coil 2 of the motor is supplied with rectified current from a transformer 3 through rectifiers 4. The armature 5 is also supplied from the transformer through the full-wave rectifiers 6, the circuit comprising limiter resistor 7, armature 6, and a trembler contact 13, 16 shunting a resistor 17 and spark-reducing condenser 18. The moving contact 13 is carried by a pivoted arm 12 connected by a spring 14 to an adjustable member 15, the spring tending to close the contact. An electromagnet 9 is energized by current derived from the armature terminals thruugh a variable resistor 11 in such sense as to tend to open the contact; whilst a part of the coil is energized in the opposite sense by the armature current, the energization being varied by a variable parallel resistor 8. The motor is started by pressing the adjustable member 15 to close the switch, and the speed increases until the armature terminal voltage rises sufficiently to open the switch and so to reduce the armature current and the speed until the spring 14 again closes the contact. When the motor is slowed down by a heavy load, the reverse winding carrying the armature current permits an early closure of the switch. In these circumstances the armature is protected against excess current by the resistor 7 which has a high positive temperature coefficient and may be of the iron-hydrogen type. The time constant and the self-induction of the motor should be small, and its speed-voltage characteristic linear.

Abstract: 814,379. Electric selective signalling. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 25, 1954 [Sept. 3, 1953], No. 24340/53. Class 40 (1). The rate of charge of a displacement is evaluated by applying a voltage, the amplitude of which corresponds to the instantaneous value of the displacement, to a rate deriving circuit of the type described in Specifications 804,906 and 804,905, [both in Group XXXV]. The voltage is composed of both a coarse and a fine component, each derived separately, and added together prior to application to the rate circuit. In Fig. 1, the voltage analogues of the coarse components are derived by the displacements of shaft 8, or device 2, by the tappings 6, 7 mounted on 8 and movable along potentiometer 4. Shaft 1b, which is geared to shaft 8 so as to rotate half of one revolution during movement between adjacent tappings on 4, controls the operation of the binary storage device 3, as described in Specification 802,799, to provide the voltage analogue of the fine displacement. The outputs of 2, 3 are added and applied to the rate device 30. The fine component is derived every second by means of a sampling pulse, applied at 33, which makes the appropriate series connections between the transformer windings 11 to In at each tapping m1 to mn. In Fig. 2, the windings l1 to In are incorporated in a binary storage device, as described in Specification 802,799, from which the voltages corresponding to the fine displacements are derived. Coarse displacement voltages are derived by the relay In + 1, the connections of which are cyclically reversed by the relay 44, the excitation of which is determined by the brush 45 which is mounted on the shaft 48 and which scans the contact series C0, C1, C2.
